[3][4] The plant is endemic to the east coast of Madagascar, specifically within the provinces of Antananarivo, Antsiranana, Fianarantsoa, and Toamasina.

The calyx is split high and has narrowly triangular parts that are very thin, with densely clothed white silky hair anteriorly, and are very open at anthesis.

The petals, if they can be called such, number 6–8 and are narrowly spathulate or linguiform, sharp, white-silky on both sides, and interposed by longer sepals.

The anthers are shortly elliptic, obtuse on both sides, emarginate at the base, attached to the back in the middle by a high stabbing, versatile, 2-lobed, and dehiscing outwards along their entire length.

The ovary is globose, sessile, completely free, and very glabrous, with 4–6 crowded, rigid, and linear styles.

The capsule is ovate-acute, 4–6 sided, and sometimes not longer than the dry calyx, occasionally exceeding 1 cm (0.39 in) in length.

They have a short, claviform cord that is stiff and hairy, and are covered with very long, silky, whitish hairs with a yellow base.

The straight embryo, the length of the seed, consists of a long stalk of cotyledons and two broadly ovate-obtuse bases.

Luckily it occurs in Bemarivo, Betampona, Makira, Mananara Nord, Masoala, and Nosy Mangabe, which are protected areas.
